HP Elitebook 840 g6: Need help identifying components

[classicandy]

Hi,

I have this HP Elitebook 840 g6 with water damage. Some resistors near the charger IC seem to have corroded. I need to replace them but i don't know their initial values.

If you have this type of motherboard, can you please measure yours and upload their values. I have circled the areas in RED. Resistor values and Charger IC values too.

Thanks

The charging chip number is not visible on the pic. Its intersil. Please specify the exact number of chip. I beleive schematic is not avlbl for this mb. So the best thing to do is to found another schematic with same charging ic and then findout the resistor with pinwise tracing.

Exactly my thoughts too. I've tried searching for alternative schematic using same IC but probably I'm not searching correctly.

Intersil 9241H
OR
ISL9241H

datasheet and the closest schematic picture is attached. But i can't get a clearer picture
